  • Page 103: Vacuum Dry And Leakage Checking

    R410A 60Hz Top-discharge Outdoor Series Technical Manual 2.Vacuum Dry and Leakage Checking 2.1 Vacuum Dry: use vacuum pump to change the moisture (liquid) into steam (gas) in the pipe and discharge it out of the pipe to make the pipe dry. Under one atmospheric pressure, the boiling point of water(steam temperature) is 100℃.
  • Page 104 R410A 60Hz Top-discharge Outdoor Series Technical Manual ③. Vacuum destroy for the second time ······ Fill nitrogen to 0.5Kgf/cm Because nitrogen is for drying gas, it has vacuum drying effect during vacuum destroy. But if the moisture is too much, this method can’t dry thoroughly. So, please pay more attention to prevent water entering and forming condensation water.

    R410A 60Hz Top-discharge Outdoor Series Technical Manual 4.Water Drainage 4.1 Gradient and Supporting 4.1.1 Keep the drainpipe sloping downwards at a gradient of at least 1/100. Keep the drainpipe as short as possible and eliminate the air bubble. 4.1.2 The horizontal drainpipe should be short. When the pipe is too long, a prop stand must be installed to keep the gradient of 1/100 and prevent bending.
  • Page 107 R410A 60Hz Top-discharge Outdoor Series Technical Manual 4.4 Convergent drainage 4.4.1. The number of indoor units should be as small as possible to prevent the traverse main pipe overlong. 4.4.2. Indoor unit with drain pump and indoor unit without drain pump should be in different drainage system.
